The Helm to Gregg transmission corridor project is a new 500-kV line extending approximately 31 miles to connect the Helm substation near the city of San Joaquin to the Gregg substation located north of Fresno. The planned line is part of the construction of the Westlands Solar Park in Frenso, CA. The facility’s anticipated output will be nearly 2,400 MW which will will need the added carrying capacity for the existing transmission infrastructure.
